Mr. Steve Lazerowich, Director, Cybersecurity Solutioning, HP Enterprise Services, U.S. Public Sector, told us, "Today, there is simply no way to provide 100% protection. As events have recently shown, it's not just the bad guys on the outside trying to gain access to your information; organizations must also be mindful of the insider threat. The best approach is defense in depth, or in other words, a multi-layered approach to protecting systems. It starts at the outer most perimeter with firewalls and network intrusion prevention systems. Systems need to be segregated on separate network segments so that a failure in one area does not expose all systems. Servers also need their own end point protection including host intrusion detection, malware protection, data encryption and white listing technology."
